He was one of six speakers announced early this morning by the DNC, and one of four current or former governors on the program.

It'll be the second time O'Malley has spoken to the convention. He gave a speech in 2004 that was remembered for its over-the-top rhetoric. ("America the beautiful, whose alabaster cities gleam undimmed by human tears; oh, my friends, to govern is to choose.")

The DNC did not say when O'Malley will take the stage. The committee also promised to unveil additional speakers and details in coming days -- which may come as a relief to other rising Democratic stars who haven't made the list. Like NY Gov. Andrew Cuomo.
